There are many cycles and changes that take place on Earth. Some occur naturally, such as tsunamis, earthquakes, tornadoes, hurricanes and volcano eruptions. These things have always been there on Earth and even such tragic things are key to life on Earth.
Other changes and cycles, on the other hand, are caused and provoked by people. These 'man-made' changes are not natural, yet they may include natural resources. Such cycles such as burning of fossil fuels (that take thousands of years of form) and the littering of land and water cause negative changes to our planet. Global warming is a main reason.
The natural changes and cycles have always taken place on Earth. And they always will, for as long as there will be life on Earth. Erosion, for instance, is a natural cycle and we cannot do anything to prevent it because otherwise, it can break all the corresponding actions that our planet does. Erosion can indeed be disturbing, especially when land changes shape and homes can be destroyed by the upcoming land cut platform.
Again, the natural cycles always have a reason behind them.
In Life, everything is connected together and if one element from an activity breaks or fails, then the whole mechanism in total with stop working, too. Earth is at the same situation. The shaping of the land due to erosion, long shore drift and deposition are all parts of a large mechanism due to which our Earth lives. If one element is removed, erosion, for instance, then the Earth as a whole may stop operating properly.
No land will be eroded and every continent will never change. Is that pleasant? It might be easier and safer for building so be built, but there is always a truth behind everything. If erosion suddenly stopped working and nothing on our Planet got eroded anymore, then the result may not be as pleasant...
Since the Atlantic Ocean expands for up to 2-3 centimeters each year due to erosion, then what could happen if there would be no erosion? The Atlantic Ocean staying the same size forever is not something that Nature intended.
If there is no erosion, then it means that there are no waves to cause an erosion. No waves mean no wind. No wind means hardly any weather. Hardly any weather may lead to droughts, famines and the prevention of crop growth. No crops? Then no farm animals, since they would have nothing to eat. No farm animals? No meat. No meat and crops? No vegetables or fruits? No biscuits or milk? Would that be a pleasant life? No...
If everything on Earth suddenly failed, then chaos may rise...Birds will not know when to migrate and where to and eventually, both animal and plant species will become extinct.
That just proves that we can never, no matter what, go against Nature.
Yet despite knowing that, we still manage to destroy bits of our beloved Planet everyday.
It might not be that obvious, but what happened yesterday is always a contribution to tomorrow. That is why everyday, thousands of plant species in the Amazon get extinct.
Why? Human activity is key.
Not everyone knows that approximately ten thousand years ago, the Sahara desert was not a desert at all! Back then, the whole of Africa flourished with fresh fruit, green and juicy grass and healthy, constant and reliable agriculture. But now, is the biggest desert on the Planet, the size of the United States of America...And it's still expanding every year.
However, everything changed when the first people of Africa have settled down. Because most ancient African tribes used the slash-and-burn method of agriculture. This means that the farmers would occupy a territory, burn all the trees and bushes and grass to leave pure soil and make room for fertile farming land. But after the land stopped producing food anymore, then the farmers had to leave it behind and occupy more land...What they left behind, didn't always recover from the burning.
As you can see, like this, humans have started destroying innocent land.
Similar human activities still take place today. In the Amazon forest, for example, poor farmers still have to burn down trees and bushes to make room for farming land, but we cannot blame them, they have to eat.
It would all be fine otherwise, but humanity is not a simple thing. We do not replant a tree for every tree that we cut down and everyday, the number of trees and bushed on Earth decreases.
There has even been a belief, among some people, that after a few decades or more than just a century, the Amazon Rain forest may instead be called the Amazon Desert.
Isn't that just tragic to even hear?
Desertification is not a major issue today, though. The thing is, that burning down trees, bushes, fossil fuels, and even coal and petrol (in vehicles) causes a worse thing: Global Warming. The act of global warming can also be defined as the Greenhouse Effect, thought it does not bring any green with it.
When smoke is released from factories, vehicles and Nuclear Power Stations, it settles our atmosphere. The gases that occupy our atmosphere due to that issue are Carbon Dioxide, Methane, The Ozone Layer in the stratosphere protects our planet from Ultra Violet radiations, so it doesn't let anything out either. So, therefore, the gases that are released cannot escape the Earth's area either.
So what do they do then? They pile up from the out layer of our atmosphere and when the gases are close by, then heat is produced. This released heat is called Global Warming and is is constantly warming up our planet. The temperatures rise in many places and even ice caps in the Arctic have started melting. This is why Polar Bears are under threat nowadays and can be extinct soon due to the melting of ice caps and the therefore destruction of the polar bears' habitats.
This is a major issue that we have to deal with in the 21st century. And what provoked it, is simply the act of going against Nature.
